throughout. I know that in the race inhabiting the Central Provinces the 
female is barred beneath at all ages. I have four specimens from Chfinda and 
the Godavari valley, all females, and there are three more in the Indian Mu- 
seum from Singbhum, Chutia Nagpur, &c. Several are evidently adults, all are 
barred beneath on the throat and breast. Indeed, I am far from sure that the 
male of the Central Indian form is not also barred, one specimen in the 
Indian Museum marked as a male from Chutia Nagpur certainly is so, but a 
male from Manbhum resembles the Himalayan bird, except that it is a little 
smaller, wing 6'75. This, however, may belong to the Eastern Bengal race, 
which is found in the Himalayas and East of the Bay of Bengal. The Indian 
form proper is, as a rule, rather smaller with a slightly smaller bill.* 
G. Lm/ardi, Blyth (fO.ptmllus olim) Ibis, 1866, p. 368, is apparently 
quite distinct, for it is said to have the anterior under wing coverts barred, 
which is never the case in adults of the Central Indian form, and, according 
to Mr. Blyth, the breast in the female of G. Layardi is not barred. A descrip- 
tion of the adult female of G . Macei from Chanda may be useful to enable 
ornithologists with better collections to determine how far the Indian form 
is separable from the Himalayan, Eastern Beugal and Burmese race. 
Upper parts bluish grey, the feathers of the rump and upper tail coverts 
with whitish edges. Central tail feathers a rather browner grey, outer tail 
feathers brown, passing into white at the tips, the white tips, being veiy 
narrow and soon worn off on the central feathers, so that they can only be 
detected in freshly moulted plumage, but increasing progressively in length 
until in the outermost restrices they are f in. to an inch long. Quills brown, 
all but the 1st narrowly edged inside and outside with white, the last second- 
aries (tertiaries) with the outer web grey. Lores dusky grey, a dark band 
from them passing through the eye and comprising the ear coverts. Lower 
plumage greyish white barred with darker grey on the throat and breast ; ab- 
domen and under tail coverts white, with a few dusky bars, further apart 
than on the breast, on the upper part of the belly and on the flanks.

Young birds have the grey of the head less pure, and the lower parts white, 
barred with dusky, the bars in some cases extending to the vent. 
If the races from Central India and the Himalaj as be distinguishable, 
it remains to be seen which is G. Macei of Lesson. The Himalayan and 
Barmese races are identical, I believe.

Two specimens from Eastern Nipal, sent to me by Mr. Mandelli, belong 
to this race, which must be added to the Birds of India. The difference
